The General Lighthouse Authorities of the UK and Ireland are conducting a survey to gauge current and future user requirements for their Differential GPS service. This was announced at the end of June 2018.

The authorities are now surveying users across a wide variety of sectors to better understand how the Differential GPS service is being used. The Differential GPS service currently provides corrections for GPS (single frequency) only, but the technology is being developed to enable corrections to be provided for all Global Navigation Satellite Systems (GNSS), should there be a requirement. The survey results will be used to establish current and future user needs.

It is important for respondents to understand that this is a survey about the
Differential GPS service and not GPS/GNSS. You can complete the survey online or download this form for offline completion.
